SPECIFICATION forming part of Letters Patent No. 291,858, dated January8, 1884.

Application filed June5,1883. (No model.)

To all whom it may concern:

Be it known that we, Tnoniis WILLiAMs and \VILLIAM A. PRESTON, citizensof the United States, residing at Princeton, in the county of Gibson andState of Indiana, have invented certain new and useful Improvements inGates, of which the following is a specification, reference being hadtherein to the accompanying drawings.

This invention relates to certain improvements in gates; and it has forits object to provide improved mechanism whereby the gate may be openedor closed from either side and automatically unlocked and locked by theoperation of opening and closing, as more fully hereinafter specified.These obj eets we attain by the means illustrated in the accompanyingdrawings, in which- Figure l is a perspective view of our improved gate;Fig. 2, a detailed sectional View of a portion of the gate, showing thelocking mechanism. Fig. 3 is a perspective view of the sliding block andbolt. v

The letters A B 0 indicate the gate-posts, the posts A and B supportingthe rails D, on which the gate travels, and the post 0 being so locatedthat the gate can close against it. The gate consists of a series ofparallel bars, E, connected by means of the vertical parallel bars F,and arranged to slide upon the rails D, before mentioned.

The letter G indicates a board secured to the rails D, just opposite thepost B. The said board is slotted, as indicated by the letter 0, theslot serving as a guide, in whichslides a grooved block, H. To the upperend of the block is secured one end of a link, I,

This rod serves to operate the gate as the 5 block is elevated ordepressed by the levers. The upper rail of the gate is notched, asshown, at two points, into which notches the bolt N falls, when the gateis fully opened or closed, securely locking it in position.

In operation the gate is carried fully to either side by the momentumgiven it by the initial movement imparted by the lever.

Having thus described our invention, what we claim, and desire to secureby Letters Fat cut, is

The combination of the parallel bars and their supporting-posts, thegate adapted to slide thereon the slotted board and sliding block andbolt adapted to sit in notchesin the gate, the levers connected to saidblock, and the pivoted rod connecting the block and gate, the wholearranged to operate substantially in the manner specified.

In testimony whereof we affix our signatures in presence of twowitnesses.
